Abstract: A weatherstrip assembly such as a glass run, and the associated method of forming the glass run, includes a body having a generally U-shaped conformation that includes a base portion, and first and second legs extending from the base portion to define a cavity. First and second seal lips extend from the first and second legs, respectively. First and second hinges are interposed between the first leg and first seal lip, and the second leg and second seal lip, respectively. The hinges are formed of a first material different than a second material of the seal lips where the first material has high elasticity, and low compression set properties.

Abstract: A method and resultant apparatus for a window seal assembly is shown and described. A thin layer of elastomer is introduced between a reinforcement member and a first surface of a window member. The subassembly of the glass member, elastomer, and rigid reinforcement is then introduced into a mold. Preferably, the thin layer of elastomer is provided by an extrusion process, such as on a metal reinforcement member, or as a co-extrusion process when an extruded reinforcement member is formed. A curable, elastomer/plastomer material is then injection molded to provide a flush glass appearance where an outer surface of the window is devoid of any seal material.

Abstract: A weatherstrip includes an elastomeric body having a first material that encapsulates a carrier. A second material having a higher hardness than the first material of the body is selectively positioned at a predetermined location in the body to support compressive loads imposed on the body. In this manner, the neutral axis of the weatherstrip can be controlled by selective location of the second material in the cross-section.
